Isotopes of hydrogen

Hydrogen (H) (relative atomic mass: 1.00794) has three naturally occurring isotopes, sometimes denoted 1H, 2H, and 3H. The first two of these are stable while 3H has a half-life of 12.32 years. All heavier isotopes are synthetic and have a half-life less than one zeptosecond (10−21 second). Of these, 5H is the most stable, and 7H is the least.

Hydrogen is the only element whose isotopes have different names that are in common use today. The 2H (or hydrogen-2) isotope is usually called deuterium, while the 3H (or hydrogen-3) isotope is usually called tritium. The symbols D and T (instead of 2H and 3H) are sometimes used for deuterium and tritium. The IUPAC states in the 2005 Red Book that while the use of D and T is common, it is not preferred because it can cause problems in the alphabetic sorting of chemical formulae. The ordinary isotope of hydrogen, with no neutrons, is sometimes called "protium". (During the early study of radioactivity, some other heavy radioactive isotopes were given names, but such names are rarely used today.)

GM HydroGen4

HydroGen4is the successor of the fuel cell vehicle HydroGen3, developed by General Motors/Opel and presented in 2007 at the IAA in Frankfurt. It is expected that automotive hydrogen technology, such as the type featured in the HydroGen4, may enter the early commercialization phase in the 2015 - 2020 time frame.

Specification

The vehicle is based on the Chevrolet Equinox and has a GM fuel cell with 440 cells and an output of 93kW. The hybrid powertrain also contains a nickel-metal-hydride battery with an energy content of 1.8 kWh/35kW and a three-phase synchronous motor with 73kW continuous power and 320 Nm of torque. The peak power of the engine is 94kW. The hydrogen tanks at 700 Bar (10000 PSI) pressure contain 4.2 kilograms of hydrogen, which last about 320 kilometers (200mi). The maximum speed is 160km/h with an acceleration from 0 to 100km/h in 12 seconds. The HydroGen4 is produced in a batch of 170 pcs from which 10 for the Clean Energy Partnership project in Berlin.

Room

A room is any distinguishable space within a structure. Usually, a room is separated from other spaces or passageways by interior walls; moreover, it is separated from outdoor areas by an exterior wall, sometimes with a door. Historically the use of rooms dates at least to early Minoan cultures about 2200 BC, where excavations on Santorini, Greece at Akrotiri reveal clearly defined rooms within certain structures.

Historical room types

In early structures, diverse room types could be identified to include bedrooms, kitchens, bathing rooms, reception rooms, and other specialized uses. The aforementioned Akrotiri excavations reveal rooms sometimes built above other rooms connected by staircases, bathrooms with alabaster appliances such as washbasins, bathing tubs, and toilets, all connected to an elaborate twin plumbing systems of ceramic pipes for cold and hot water separately. Ancient Rome manifested very complex building forms with a variety of room types, including some of the earliest examples of rooms for indoor bathing. The Anasazi civilization also had an early complex development of room structures, probably the oldest in North America, while the Maya of Central America had very advanced room configurations as early as several hundred AD. By at least the early Han Dynasty in China (e.g. approximately 200 BC),comfort room complex multi-level building forms emerged, particularly for religious and public purposes; these designs featured many roomed structures and included vertical connections of rooms.

Asterisms

Room (magazine)

Room (formerly Room of One's Own) is a Canadian quarterly literary journal that features the work of emerging and established women and genderqueer writers and artists. Launched in Vancouver in 1975 by the West Coast Feminist Literary Magazine Society, or the Growing Room Collective, the journal has published an estimated 3,000 women, serving as an important launching pad for emerging writers. Currently, Room publishes short fiction, creative non-fiction, poetry, art, feature interviews, and features that promote dialogue between readers, writers and the collective, including "Roommate" (a profile of a Room reader or collective member) and "The Back Room" (back page interviews on feminist topics of interest). Collective members are regular participants in literary and arts festivals in Greater Vancouver and Toronto.

History

The journal's original title (1975-2006) Room of One's Own came from Virginia Woolf's essay A Room of One's Own. In 2007, the collective relaunched the magazine as Room, reflecting a more outward-facing, conversational editorial mandate; however, the original name and its inspiration is reflected in a quote from the Woolf essay that always appears on the back cover of the magazine.
